The weight loss show "The Biggest Loser" follows the stories of a group of obese individuals assisted by professional trainers to lose large amounts of weight. Each contestant competes for the title and prize money, weighing in each week after intense workouts. If you watch each week and want to figure out the total percentage of weight lost for each contestant or group of contestants, you can use a simple formula to calculate the percentage of a number.
Determine the number of pounds lost and the starting weight of the contestant.
Multiply the total number of pounds lost by 100.
Divide the sum by the contestant's starting weight.
